To all whom it may concern.'l

Be it known that I MARIoFERNANDnz ARIAS, a. subject of the liing of Spain, and a resident of Newark, in the count of Essex and State of New Jersey, Uni States of America, have invented a new and Improved Cushion Seat, of which the following is a full, clear, and exact description.

This invention has relation to seats for chairs, stools or the like and primaril aims to rovide a seat which will ive the esired cus ioning effect without bul ess.

l plates a cushion seat which is provided on its renti@- As a further object the invention vcontemunder surface with means for defining a plurality of air pockets when applied to the chair or-stool which function to enhance'the cushioning effect of the Seat, prevent casual displacement ofthe seat from the chair bot` tom, while at the same time allowing for a. sufficient amount of play or movement in the seat to prevent friction between the same and the clothing'1 of the user.

AAs a. still furt er object the invention contemplates' a cushion seat of the character set forth which is extremely simple .in its construction, inex ensive to manufacture, and which is hig y efficient in its purpose.

With the aboverecited and other ob3ects in view, the invention resides in. the novel construction set forth in the following speciiication, articularly pointed outin the appended c aims and illustrated inthe accompanyin drawings, it being understood that the ri tis reserved to embodiments other than t ose actually illustrated herein to the 'full extent indicated E,by the general meaning of the terms in which the `claims aref expressed. n

Figure 1 is atop plan view of a cushion seat constructed in accordance with the in- Fig-.2 ist. hamm piantiew thereof;

. Fig. 3 is across' sectional lview therethrough taken approxin'iatelyv :on the line' indicated at 3-3 1n Fig. 1.

Fig. -4 is atop plan view of a'modified form of the invention.

Fig. f5 is a bottom plan view thereof.

Fig. 6 isa fragmentary cross Sectional view thereof taken .approximately on the line 6 6 of Fig. 4.

Referring to the drawings by characters of reference, the cushion seat comris a piece of materialv 10 which em ies the characteristics of sponge rubber and which 1s formed on its un er face with a pluralit of endless ribs 11 preferably integral wit the body 10 and paralleling the marginal edge ofthe same to define between said ribs a .plurality of endless recesses 12, which, when the seat is arranged on the chair bottom, define closed air pockets for enhancing the cushion effect of the material from which it is constructed, and which further function to prevent casual dis lacement of the Seat from the chair while a lowing for a suicient pla or movement of the same to rub ing or friction between the clot -in of the user which would tend to produce a s ine on the garment. Preferably the upper face of the body 10 is lined with a. fabric 13.

n In the modified adaptation of the inven tion illustrated in Figs. 45 and 6 the body 10a is of substantially circular formation and 1s formed with a plurality of concentric endless ribs 11 on its under face which define a plurality ofconcentric recesses 12a which further define air pockets on the stool S when the cushion seat is applied thereto.

In this form v it is found preferable to provide the marginal edge of the cushion seat with a depending contractile iange 14 which is adapted'to embrace the edge of the stool Sv for the purpose of retaining the cushion seat in .place thereon and against -displacement prior to the imposition ofthe the material from whichit' 4is constructed revent so s;

05 rubber and formed with a plurality o endless'ribso'n its under face allellng'the mar v'n ofthe body and defining A together with vt e article .upon which it 1s superimposed a-plurality of closed air pockets for enhancingxthe cushioning effect of p21-rf and for preventing casualfdisplacement .of l

the Same 'from said .article when the weight of the user is imposed thereon. I

which it is superimposed a plurality vof closed air pockets for enhancing the cushioning effect of the material from which it is constructed and for preventing casual displacement of the same from said article when' the Weight of the user is imposed thereon.

3. A cushion seat comprising a body construct/ed of a material having the qualities of sponge rubber and formed with a plurality of endless ribs on vits under face paralleling the margin of the body and definin together with the article upon' which it is superimposed a plurality of closed air pockets for enhancing the cushioning eiect of the material from which it is constructed and 15 for preventing casual displacement of the same from sald article when the Weight of the user is imposed thereon, and a contractile marginal depending ilange on said body for engaging the edge of a stool to assist in pre- 20
